FLOUR CARTON AND SIFTER THEREFOR Filed Oct 2a. 1958 ENTOR ATTORNEYS Patented Dec. 10, 1940 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to sifters, and more particularly to a sifter adapted to be attached to and form a part of a suitable dispensing carton.

' An important object of my invention is to provide a sitter that is simple in construction, em-

cient in operation, and inexpensive to manufacture. v c

-A further object of my invention is to provide a sifter carried by and forming a part of a suitable carton.

A still further object of my invention is to provide a'sifter adapted to sift the contents of a dispensing cartomwithout having previously removed the contents therefrom.

Other objects and advantages of my invention will be apparent during the course of the following description.

In the accompanying drawing, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a perspective view of a device embodying my invention, as seen from the Lmder side of the carton flap to which it is attached,

Figure 2 is a perspective view of the same as seen from the exterior thereof,

Figure 3 is a view in perspective showing the device embodying my invention in operative position,

I 30 Figure 4 is a similar view showing the carton with all flaps closed, and

Figure 5 is a fragmentary sectional view taken on the line 5-5 of Figure 3.

1n. the drawing, wherein for the purpose of il- 35 lustration is shown a preferred embodiment of my invention, the numeral 10 designates a carton for dispensing flour or the like, formed with folded end flaps ll, l2, l3, and it. The flaps and [2 are provided with registering openings l5 and I6 respectively.

Stapled to the underside of the flap l2 and covering the opening It is a flnewire mesh or screen l1. Slidably journaled in the staples I O and in close frictional engagement with, the underside of the screen I I is an agitator which is disposed diagonally of the carton I l and has the end 20 thereof projecting exteriorly of the carton (Cl. ans- 351) at the comer 2 I. The end 20 is of angular formation to permit it to be conveniently held while operating the agitator.

The operation of my invention is as follows.

The end flaps l2 and H are folded inwardly in the conventional manner and the side flap H folded in so that the opening 15 registers with the opening it as illustrated in Figure 3. These flaps are then securely bound together by means of glue or the like. The flap I3 is then folded over 10 and secured in any way desired as illustrated in Figure 4. When it is desired to secure a part of the contents of the carton l0, it is necessary to raise only the flap I 3, invert the carton over a measuring cup or the like, impart a reciprocatory 15 movement to the agitator l9, and the contents of the carton are poured and sifted in a single operation.

It is to be understood that the form of my invention herewith shown and described, is to be 20 taken as a preferred example of the same, and that various changes in the size, shape and a1;- rangement of parts may be resorted to, without departing from the spirit of my invention or the scope of the appended claim.

Having thus described my invention, I claim:

In a preformed carton having a rectangular cross-section of the type having folded end flaps, certain of the innermost flaps having registering openings and the outermost flap being imperforate in a manner to close the said openings, a perforated element covering the openings in. the innermost flaps, and an agitator disposed diagonally of the carton across the said openings and arranged for sliding movement relative to the perforate element, a part of the said agitator extending from the carton through the interstice defined by the folded end flaps and comprising a fln'gerpiece, whereby lifting of the said outermost flap to uncover the openings and manual actu- 0 ation of the agitator through the medium of the flngerpiece will permit the contents of the carton to be simultaneously discharged and sifted and without necessitating the shaking of the said carton. 5
